Graph a temperature monitor

Note: This example is provided as an illustration only and is not supported. Technical support is available for the Context object, SNMP API, and scripting environment, but Ipswitch does not provide support for JScript, VBScript, or developing and debugging Active Script monitors or actions.

This performance monitor polls an SNMP-enabled temperature sensor using the CurTemp reference variable.

A typical graph for this script:

// This script is a JScript script that polls the temperature of an snmp-enabled sensor from "uptime devices" (www.uptimedevices.com).
// It uses an SNMP reference variable named CurTemp defined with an OID of 1.3.6.1.4.1.3854.1.2.2.1.16.1.14
// and an instance of 1.
//
// That device indicates the temperature in degrees Fahrenheit.

var oCurTemp = Context.GetReferenceVariable("CurTemp");
if (oCurTemp == null) {
Context.SetResult(1, "Unable to poll Temperature Sensor");
}
else {
// convert temperature from tenth of degrees to degrees
var nFinalTemp = oCurTemp / 10.0;

// comment out the line below to convert the temperature in Celsius degrees:
//nFinalTemp = (nFinalTemp - 32) * 5 / 9;
Context.SetValue(nFinalTemp);
}
